Currently, when you want to add an image to a page using Site Builder, you are presented with the "My Library" interface. Within this library, it would be helpful to have several features:
1) Search your library. The current search feature searches an external site. I would like to be able to search my library, including tags.
2) Preview image info. I sometimes have similar but slightly different files to use. I would like to be able to at least see some basic info about an image besides just it's size. It would be helpful to see the filename at a minimum, as well as the extension (I save transparent logos in PNG and non-transparent in JPG, for instance).
